A device for taking specimens for laboratory analysis, specimens being of a fluid type such as body liquids or may be liquids of a different source. The device comprises a hollow body member with a closed end and an open end. The closed end has orifice therethrough which orifice is eccentric with respect to the longitudinal axis of the body member. A plunger having a plunger tip means is inserted into the body member for the purpose of accurately varying the internal volume of the device. The closed end is provided with an exteriorly mounted closure which may be of a rotatable type or a sliding plate type. The closure contains an orifice which may be aligned with the orifice in the closed end to take specimens into the device and then the closure may be moved with reference to the body member to misalign the orifices so that the orifice in the body member is closed and the specimen cannot be ejected from the device. Sealing means are provided between the closure interior and the exterior of the closed end around the orifice in the body member. The present embodiment of the invention includes the presence of an agent which is applied to the collected specimen for the purpose of maintaining it, culturing it, or defining the composition of the specimen. The agent may be placed on the interior of the hollow body member in which configuration it contacts the specimen immediatedly upon the entry of the specimen into the hollow body. The agent may be placed in a recess on the interior of the closure which recess is brought into registration with the orifice in the closed end only by movement of the closure so there is subsequent contact between the agent and the specimen. This avoids any communication between the specimen source and the specimen agent or specimen after its contact with the agent. There is also disclosed a novel plunger having a pivotal member on the stem of the plunger which engages the open end of the hollow body member of any type of syringe to prevent accidental ejection of a collected specimen.
